Creating Screencasts/Technical issues

File Size Before starting a screencast, you want to make sure you will have adequate space to store the final video. It's generally a good idea to have at least double the space you think the resulting video will be. Controlling Video File Size Not all these options may be available to you when recording and may instead be hard-coded into the software as presets. Resolution This is the size of your video's width and height in pixels. Generally, more pixels = more memory, so having a larger resolution will result in a larger file size. Capture rate How often a frame (still picture) is recorded. This is usually denoted in milliseconds (ms). A lower capture rate will result in more frames being captured during a given interval of time. Framerate This represents the amount of frames played in a given time period. Usually it is denoted with frames-per-second (fps). Bitrate The maximum amount of data allowed to be recorded at a given time. Usually measured in Kb/S. Compression \ Codecs The encoding scheme used to store the video. Keyframes This stands for whole or complete frames. Easy on the eyes Fullscreen VS region recording. Maintaining a descent file size without sacrificing readability in compression. Controlling Audio Size Channels (mono vs stereo) If you're just recording your voice from a microphone, mono (single channel) is recommended. Frequency Measured in Hertz Bitrate The maximum amount of data allowed to be recorded at a given time. Usually measured in Kb/S. Compression The encoding scheme used to store the audio data.
